Effects of covering portion of an axial fan blade?
(OP)
In a scenario an axial fan is positioned on the top of a box drawing air in from three of the four vertical faces. A portion, lets say a fifth, of the fan blade is covered by some metal on the bottom of the fan closest to the middle of the three face openings. Will this effect the airflow through this open face much?

Fans require even flow to load the wheel or blade evenly. Look at old style IGVs on cent. fans, the vortex damper allows to even out the flow.
